Base Class: Barbarian
Spellcasting
When you reach 3rd level, you evolve your rage with the ability to cast spells.
Cantrips. You learn two cantrips of your choice from the Wizard spell list. You learn an additional cantrip of your choice at 10th level.
Spell Slots. The Battle Caster Spellcasting table shows how many spell slots you have to cast your spells of 1st level or higher. You regain all expended spell slots when you finish a long rest. Spells known of 1st level and Higher. You know three 1st-level Wizard spells of your choice, all of which must be from the schools of Abjuration and Transmutation. The Spells Known column of the Battle Caster Spellcasting table shows when you learn more spells of 1st level or higher. Each of these spells must be an Abjuration and Transmutation spell of a level you have the spell slots for.
Whenever you gain a level in this class, you can replace one of the spells you know with another spell of your choice from the Paladin or Wizard spell list. The new spell must be of a level for which you have spell slots, and it must be an Abjuration and Transmutation spell. Additionally, you may not learn any spell that is capable of regaining Hit Points. Spellcasting Ability. Constitution is your spellcasting ability for your spells. You use your Constitution whenever a spell refers to your spellcasting ability. In addition, you use your Constitution modifier when setting the saving throw DC for a spell you cast and when making an attack roll with one.
Spell Save DC = 8 + your proficiency bonus + your Wisdom modifier
Spell attack modifier = your proficiency bonus + your Wisdom modifier

- Your Rage doesn't end early if you have cast a spell on your turn.

At 6th level, you gain the ability to imbue your weapon strikes with magical energy. Once on each of your turns when you hit a creature with a weapon attack, you can have the attack deal an extra 1d8 force damage. When you reach 13th level, the extra damage increases to 2d8, and at 19th level the extra damage increases to 3d8.
---Reserve of Rage
At 14th level, while you rage you are capable of tapping into hidden arcane power. You gain an additional first level spell slot and second level spell slot that are only accessible to you while you are raging. Like your regular spellcasting, once you have used one of said spell slots, you may only regain it after a long rest. At 18th level, you gain another first level spell slot and a third level spell slot accessible to you while raging.
